To all 1071 0m it may concern:

Be it known that we, CHARLES Lnwis GRUNEISEN, of 39 Amberley road, Falmers Green, in the county of Middlesex, England, and JOHN THOMAS HIRCOCK, of 36 Powell street, Finsbury, in the county of London, England, both subjects of the King of the United Kingdom, have invented certain new and useful Improvements in Attachments to Casing-In Machines Used in Bookbinding, of which the following is a specification, reference being had therein to the accompanying drawings. 7

Our invention refers to certain machines used in bookbinding operations known in the trade as casing-in machines, which operate by taking the outside covers, technically called cases or casings, and applying them to the books they are to bind by pasting. Both the books, and the casings, are now usually made up apart from the casing-in machine, and are brought to and placed on the machine in an appropriate position for the operations following. The function of the casing-in machine is restricted therefore, to pasting the two side surfaces of each book ready to receive a cover, feeding the cover or casing from a magazine or receptacle (arranged to hold a number of them) to its required position over the book, raising the book up within its casing, forcing the flexible back (or central part between the two lids) down upon the back of the book and into the joints or hinge line of the lids, then applying pressure to the outside of the two lids so that they arefirmly attached on their inside surfaces to the pasted surfaces of the book, and then delivering the finished product to its appointed part of the machine, ready for taking away.

The object of this invention is to increase the etficiency and output of casing-in machines, especially when used in the production of books less in size than the maximum for which the machine is intended. To this end we employ certain devices attached to and embodied in a casing-in-machine and in combination with the elementsof the latter, whereby books of any size within the scope of the-machine may be incased with equal swiftness, the output being practically constant whatever the'size of the book: and

our invention consists in the construction and combination of the said devices-as here.-

vtable in the required position. table ar? for the books is also shown by plan inafter more particularly set forth and claimed.

This improvement is designed especially to be used in and with machines of the type described in the patent of Frederick D. Taylor granted December 30th, 1902, No. 716,959.

Our invention consists in the construction and combination of parts hereinafter more clearly set forth and claimed, in the further description and illustration of which we refer to so much only of this machine as is necessary.

Figure 1 is a partial elevation of such parts of a casing'in machine as are directly connected to and combined with our improvements, other known parts being omitted for clearness. Fig. 2 is a plan of the feeding table, two out of the three rotatable arms being shown by diagrammatic lines only. Fig. 3 is a plan of the principal parts of the table of the machine shown in Fig. 1, the general position occupied by the ma gazine of cases being indicated by two dotted lines. Fig. 4 is a side elevation. and Fig. 5 a plan of a back pusher, and Fig. 6 is a side elevation, and Fig. 7 a plan of a front pusher. Fig. 8 represents three details of a spring wire presser foot. Fig. 9 is a side elevation of a pivoted spring stop. and Fig.

10 a plan of its spring bar carrier. The Figs. 4 to 10 inclusive are drawn to a larger scale than the others.

At the left hand side of Fig. 1 a suitable bracket a is secured at an angle to a part of theframe a to carry a slide a and feeding table a at an angle turned toward the reader; both the slide and table being adjustable vertically, to suit the size of the cases or covers, by hand wheel and screw a. a screw and nut being indicated by clotted lines, while a clamping nut shown on the face of the slide serves to secure the The feeding Fig. 2 at a different angle to Fig. 1, and carries two sides aid adjustable to and from the central part of the table by a right and left' hand screw (as indicated by dotted lines) working beneath the table a in corresponding nuts. forming a part of or attached to the sides the protruding ends of the adjusting screw working in the bear- 11lgS (Z- This gives transverse adjustment to the sides a across the table a to suit the thickness of the unbound book a, and facilitates feeding them two at a time through the trough as indicated in Fig. L W n In the ordinary way, the books are fed by hand, the attendant dividing the-leaves centrally by skilful touch so that each half or side of a book may hang truly metrically upon the arm to insure pastingv the outside leaves equally and eflic'iently to insure good work. But. with double the number of books to be handled in the same time as before it would bemore difficult to open each book correctly in the center, place it on thearnnth andslide it-accurately up to the gage. \Ve there-foresee up a separate pilot finger or tapering knife-Pedged blade 6, in the center of the feeding table 0& (Figs; 1 and 2), close to the rotatable arm I), and by pushing twobooksat a time through the trough ar', the blade bis brought against the center of the leaves of eachbook, thus opening it truly in the middle,- and enabling bothbooks to slide over it and on to the" arm 6 over an improved formof adjustable duplex gage Z2 3, on each' arm having a tapering edge on the book entry side, instead of the square one hitherto used, the front book being arrested inits proper position by the stop (2 and the second book brought back slightly by the hand of the attendantagainst the inner side of b as a stop, to their respective positions as shown on the arm- 6 which is assumed to have been already rotated into that position ready for the pasting process.

The maximum size of case thatcan be used for binding books is controlled by the width of the arm which carries the" book during the pasting process; but our improvements are'intendedfor casings or covers only one half or less of the capacity in width of the arm. In the machine under notice three similar arms are mounted on a cylinder b (Figs. 1- and-2),atequal angles of 120 around its circumference. The cylinder is intermittently rotated by the special mechanism of the machine and each plate or armflin succession is lowered together with its book to be pasted at the designed position, by devices that are shown and describedin the U. S. Patent No. 716,959, and are therefore omitted herein. The three arm's we indicate 'by b b and b the latter two by diagrammatic lines only in Fig. 2; while inFig. 1 the arm or plate 12'' is shown as carryingthetwounbound books a a in their required position against the adjustable gage b and stop bfl ready for the pasting process as already stated.

At the right hand side ofFig.- la maga' zine or receptacle-c is shown as containing a pile of cases-, (indicated by lines-a prepared elsewhere, jready," to'- be pasted V to the b k E ch S 'aar t eo- 'r ora esec s; r9-

moved from the pile at the bottom of the magazine by the reciprocating action of two pushers cl, (Z working on slides on the frame beneath the magazine, one on each side of the machine, and shown-"more clearly on the right hand side of Fig. 3. Each pusher is furnished at its forward end with a pusher plate d adjustably secured by screws to the carriers cl, as shown on the enlarged scale elevation Fig. 6 and plan Fig. 7, and carries apair of thin spring plates 61 and (l the lower one, (Z forming a slightly projecting. lip adapted to pass under the bottomsurface ofthe bottom case in the magazine, while the upper plate or lip (Z is thickened and adapted'to strike against the edge thickness of the bottom case and push it out from under the pile of cases, a in the magazine, which is formed to allow of this. This device, now placed in front of the formerly used pair of pushers, is' an impoi'tant part of our invention, and if at any time-it is desired'to bind books on the machine the cases of which are of the full capacity in width of the machine, or'indeed of any size exceeding one half the said dimension, it would be necessary to remove ourfront pair of pushers before reverting to the use of the wider cases. H

In the side elevation Fig. at, and plan Fig. 5, we show on the same scale as Figs. 6 and 7 an improved back pusher, the plate 6 being secured to the carrier plate (Z by two screws through the holes 6 c and (Z on each side of the machine. The spring lip of the back pusher c is slightly modified by turning over the front edge of the lower lip 6 so that it may pass freely beneath a case on entering" the magazine until contact is made with the upper spring lip 6 which projects sufliciently for the purpose of pushing out the second casedu'ring the forward reciprocating motion of the carriers; A small spring is arranged on the pivot of each upper lip (Z and 6 as shown in Figs. 7 and 5 respectively; and an adjustingscrew e under the lip 6?, thus alsoproviding for changes in the thickness of the covers or casings. But as a similar pair of pushers in this position has hitherto been used for the'function of removing cases of all sizes fromthe 1nagazine,-we only claim them in combination with the front pair of pushers. The relative positions of the front pushers (Z, (Z and d and the back pushers e, e and e are shown in the partial plan-onthe right hand of Fig. 3,-the magazine and all nonessential parts being omitted for clearness. On thelefthand of the samefigure, a partial plan isalso shown of the relative positions of two'coversorcasings a a where they have been left by a previous reciprocating motion of V the a front and back pushers: Is -th p ition t eya er a y to be l lo placed over and rolled or pressed down upon the sides of the books a a as soon as the latter are pasted, and then' become ready for removal as bound books.

A spring bar presser foot 7 is shown as pressing the two cases a a (Fig. 3) down to the exact position required and to which they were moved by the front and back pushers, the presser foot being shown by the three details on a larger scale in Fig. 8. The details of Fig. 9 and Fig. 10 also indicate on a larger scale the pivoted spring stop g, holder g and spring bar 9 While the spring stop g, sliding freely over the surface of each case as it comes from the magazine, drops down after its passage and prevents it being drawn back by friction contact on the return of the pushers.

As shown in Figs. 3, 9 and 10 the spring bar 9 consists of a straight rod held at right angles to stop 9 and an integral short arm at the inner end of said rod bent so as to be presented in line with said stop and holder g and screw-clamped to the top of the latter. The stop g is a bar in line with said holder and pivoted thereto at their proximate ends, permitting vertical pivotal movement of said stop which is presented in the direction of feed of the cases.

What we claim and desire to secure by United States Patent is:

1. In a casingin machine, means for feed ing from a suitable magazine or receptacle two cases or covers at a time by a forward reciprocating motion of the feeding device, in combination with an adjustable feeding table provided with means adapted to receive and pass on two unbound books to the required position for pasting them and applying their respective cases or covers, substantially as and for the purpose shown and described.

2. The combination, in a casing-in machine for binding books, of a pair of front pushers, each having a pusher plate and a pair of spring plates, the upper plate of this pair being adapted to push out the bottom case from a pile of cases, and a pair of back pushers, each having a lower lip which may pass beneath a case in the magazine, and an adjustable upper spring lip which projects sulliciently to push out the second case.

i 3. The combination, in a casing-in ma chine for binding books, of a bracket or support a, carrying a vertical slide a and feeding table a with means a for adjusting the table vertically, sides a adjustable by means a, and a pilot finger or blade 6 for dividing the leaves of the books evenly, sub stantially as and for the purpose shown and described.

4. In a casing-in machine for binding books, the combination of a series of arms for carrying the books, means for feeding books in pairs to each arm successively, a pair of stops at the ends of each arm to regulate the position of the books thereon, leaving a suitable interval between them, pushers for feeding cases to said books, means for holding a pair of cases in the position to which they have been moved by said pushers, and a spring stop and supporting devices therefor, said stop being arranged to slide freely over the surface of each case as it comes from themagazine and to drop down after the passage of said case, preventing it from being drawn back by frictional contact with the pushers.

In testimony whereof we have afixed our signatures in presence of two witnesses.
